Ice Cores Record Long-Ago Seasons in Antarctica

by Caroline Hasler 17 March 202316 May 2023

Researchers used ice core data to reconstruct seasonal temperatures throughout the Holocene. The results link especially hot summers with patterns in Earth’s orbit.

How Kicked-Up Dust Forms Cirrus Clouds

by Morgan Rehnberg 14 March 202320 April 2023

Dust lifted into the air by cyclones provides anchor points for cloud-forming ice.

A large, dark cloud is contained within the frame. In its top half it is textured like smoke and has wispy gaps, whereas at the bottom and on the sides it fades gradually out of view. On the left are several orange stars: three each with six large spikes and one behind the cloud, which colors it pale blue and orange. Many tiny stars are visible, and the background is black.

Complex Organic Ices Discovered in a Star-Forming Cloud

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 24 February 20231 March 2023

The presence of complex organic molecules such as methanol, ethanol, and acetaldehyde in a molecular cloud suggests that these and simpler ices might be available to planetary systems right from the start.

Mission Could Lasso Amino Acids from the Icy Plumes of Enceladus

by Isabel Swafford 13 December 202213 December 2022

If geysers from Saturn’s moon Enceladus contain amino acids, new research shows that a spacecraft could collect them with signatures of possible life preserved.

Alaskan Glaciers Advance and Retreat in Satellite Imagery

Katherine Kornei, Science Writer by Katherine Kornei 12 September 202212 September 2022

Researchers tracked 19 maritime glaciers in Kenai Fjords National Park over several decades and found that tidewater glaciers tended to experience less ice loss than other types of glaciers.

Modeling the Ice Flow and Evolution of Glaciers

by Harry Zekollari 31 August 202219 January 2023

Glaciers are crucial water resources and important sea level contributors. To accurately model glacier evolution, their mass balance and ice flow processes must be accounted for.
